I thought that you might be interested in an on-line publication that the Careers Development Institute has recently published. It pulls together twelve monthly articles that David Andrews has written about the role of the Careers Leader.
I have had the opportunity of hearing David present over the years on the delivery of careers in schools and he has developed a reputation as one of the leading thinkers in this field. His musings are very much based in reality and he has developed his thinking in line with the many changes he has worked with over the years in how careers is delivered.
Hopefully you will find something that you can draw on and help you develop your implementation of careers.
